This data sheet provides detailed information on Fujitsu MB90460 series 16-bit proprietary microcontrollers, which are designed for process control applications that require high-speed real-time processing, such as consumer products.
The MB90460 series is a line of general‑purpose 16‑bit microcontrollers from Fujitsu designed for process‑control and consumer‑product applications that require high‑speed real‑time processing. The devices inherit the AT architecture and add instructions for high‑level languages, extended addressing modes, and enhanced arithmetic operations, including a 32‑bit accumulator.
The manual details the series' peripheral resources such as A/D converters, UARTs, multiple timers, and programmable I/O, lists available package types (64‑pin QFP, LQFP, SH‑DIP), provides electrical characteristics, pin‑assignment diagrams, and compares the different product variants within the series.
